• Nicole Richie, dancing in her seat in her balcony perch during deejay Mark Ronson's show at Los Angeles's El Rey Theater. There with her beau Joel Madden, the pregnant starlet also watched British popster Robbie Williams sing as Ronson played guitar. Afterward, Richie and Madden took the elevator down. "She was precious," an onlooker tells us. "She has that pregnant glow." Also at the concert: Mischa Barton.

• Brooke Shields, sharing mommy tips with new mother Bridget Moynahanduring a date at Barneys New York in Beverly Hills. The pair lunched together at Barney Greengrass, giggling and talking over their sandwiches and salads. After the meal, it was time for some retail therapy at the store.

• With Paris swept up by Fashion Week events, Bruce Willis hit up the city's boutiques during a visit to the City of Light. The actor surprised pedestrians on Rue St. Honore as he shopped solo, carrying a Dior bag.

• Also in Paris – for all the fashionable events – Kanye West and fiancée Alexis Phifer, arriving arm-in-arm with designer Karl Lagerfeld at a party at the V.I.P Room on the Champs-Elysées to celebrate a French edition of Playboy. The pair – plus the designer – sipped Dom Perignon and chatted with magazine covergirl Vahina Giocante. Also sipping bubbly at the fete: fellow fashion show attendee Courtney Love.

• Heather Graham, celebrating her indie flick Broken with a Hpnotiq-sponsored party at D'Or, a club inside Amalia eatery in New York. The actress, who danced up a storm to Rihanna's "Umbrella," was joined by castmates including Jeremy Sisto at the bash. At one point, photographers wanted to snap her picture, but Graham asked that they hold off for a minute so she could finish dancing.
